Aim:
Study of advantages of retrobulbar anesthesia and its complications in posterior
vitrectomy using 0.5% bupivacaine with lidocaine 2%
Materials and Methods:
Number of study patients: 1000 patients who underwent a retrobulbar anesthesia
using
a combination of 4 ml bupivacaine 0.5% + 6 ml lidocaine 2% for a Pars-planaposterior
vitrectomy.
Results:
Patients aged between 16-85 years, 55% of whom were males and 45% females, the
indications of the Pars-plana vitrectomy were: 45% diabetic retinopathy, 15% macular
hole, 10 lens-luxation , 7% artificial lens dislocation, 5% chorioiditis,5% posttraumatic
vitreous haemorrhage , 5% macular pucker, 5% rhegmtogenous retinal detachment, 5%
intraocular foreign body, 0.5% endophthalmitis. Complications: 0.4% retrobulbar
hemorrhage, 2% elevated intraocular pressure, 0.2%, expulsive choreoidale haemorrhage,
pain 8%, fear, anxietyand tension 0.2%, eyelid haematome 4%, patient movement 1.3% ,
diplopia 1%, ptosis 1,3%, low heart rate and low arterial pressure 0.3%.
Conclusion :
retrobulbar anesthesia is recommended with the combination of bupivacain and
lidocaine in the posterior vitreorectomy, with some exceptions such as drug allergies,
single eye, high myopy, advanced optic nerve lesions, children, no coopertion.
Background: Lidocaine had shown to inhibit neural conduction and antiinflammatory
properties. The purpose of this research was to study the effect of using
intravenous lidocaine with general anesthesia drugs on opioids and inhaled anesthesics
cons
umption during surgery and the require of analgesics after surgery.
Setting: This study was carried out in the department of anesthesia and reanimation
at Tishreen University Hospital, Lattakia, Syria during 2017-2018.
Type of study: Double-blinded randomized comparative study.
We performed this study aimed to compare the sensitivity of
parasite detection by microscopic examination in samples collected
by conventional technique and samples collected after local
anesthetic with lidocaine and adrenaline of the same lesions in
patients with suspected leishmaniasis.
This study was performed to investigate the analgesic effects of lidocaine ,
Xylazine and Lidocaine / Xylazine combination in eye regional anesthesia.
Twenty four goats were randomly designed in 4 groups .
to compare the anesthetic efficacy of 4% Articaine
HCL with 2% Lidocaine HCL, both with epinephrine 1:100,000, in
truncal block of the inferior alveolar nerve during the surgical
extraction of impacted lower third molars.
Usually, dentists search for methods to provide a painless treatment using local
anesthesia. The aim of the study is to evaluate and compare the anesthetic efficiency of three anesthetics
used in dental practice in Damascus, in both maxillary lateral incisor and first molar.
